Hi idk if this is the right place to get help. My laptop model is np305U1A i've been getting black screen for the past few days nothing is showing up the power led is on and the caps lock led is lit cant turn it on or off. My battery is broken and im just using the charger the laptop came with (i've been doing this for a year). So heres what happened i went to my browser did tried to type but suddenly my keyboard just doesnt work so i tried restarting it then it got stuck on the restarting logo for like an hour so i decided to unplug the charger then the black screen happened so PLEASE HELP! I WOULD REALLY APPRECIATE IT

Ps i already tried unplugging it from the charger and removing the battery and holding the power for 1 min but it still didnt work

Hi,

Here are some troubleshooting steps that I suggested to others who had the same concern.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.
